Some may ask why this is special to any degree. Well, if you notice the wire groove it's the deep variant that you generally see on later production. Finding a B with drips is somewhat of a challenge to be had but the deeper wire groove on top of that makes it even tougher. I've also had several people say that the "B" embossing isn't present but rather you just have to know where to look for it when the embossing are super weak...
